Abstract

The invention discloses a deviation correction method and device for an atmospheric pollution source emission list, and a storage medium. The method comprises the following steps: dividing a target region into a plurality of areas; calculating the average relative deviation of the atmospheric pollutant concentration of each area based on the atmospheric pollutant data of each area in the preset historical time period; acquiring the mutual contribution rate of the atmospheric pollutant concentration between the areas; acquiring atmospheric pollution source emission list system deviation of eacharea based on the average relative deviation and the mutual contribution rate; and correcting the original atmospheric pollution source emission list of each area by utilizing the atmospheric pollution source emission list system deviation. According to the method, the atmospheric pollution source emission list system deviation of each area is calculated based on the average relative deviation and the mutual contribution rate, the original atmospheric pollution source emission list of each area is corrected, the influence of the mutual contribution rate is considered, and the correction result is more accurate, so that the model prediction accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of air quality monitoring, in particular to a deviation correction method, device and storage medium for an emission inventory of air pollution sources. Background technique [0002] The emission inventory of air pollutants is the basis of air quality forecasting and pollution control measures and policy simulations. The certainty of the emission inventory and the degree of refinement of the distribution of time, space, and chemical composition directly affect the effect of forecasting and simulation. At present, the emission inventory has great uncertainty, and it is necessary to correct the emission inventory according to the effect of the model forecast to reduce the uncertainty and improve the accuracy of the model forecast. [0003] At present, the commonly used method of emission inventory revision is to compare and verify the effect of forecast and observation data in each region. Without co...
